This study aimed to evaluate the potential of long noncoding RNAs (lncRNAs) as biomarkers for coronary artery disease (CAD). We measured the levels of three atherosclerosis- or cardiac-related lncRNAs in peripheral blood monocyte cells (PBMCs) from 20 CAD patients and 20 non-CAD control participants using real-time reverse transcription-polymerase chain reaction (real-time RT-PCR) methods. We found that the levels of lncRNA KCNQ1 opposite strand/antisense transcript 1 (KCNQ1OT1), hypoxia-inducible factor 1 alpha-antisense RNA 2 (HIF1A-AS2) and apolipoprotein A-1 antisense RNA (APOA1-AS) were significantly increased in CAD patients (KCNQ1OT1 increased by 2.

Our previous data confirmed that 1,8-cineole ameliorated the inflammatory phenotype of human umbilical vein endothelial cells (HUVECs) by mediating NF-κB expression . At present, we investigated the protection effects of 1,8-cineole on vascular endothelium in lipopolysaccharide (LPS)-induced acute inflammatory injury mice and the potential mechanisms involved in the protection in HUVECs.

Objective: To assess the value of high-resolution magnetic resonance imaging (MRI) and three-dimensional (3D) reconstruction of the trigeminal nerve and the superior petrosal vein (SPV) in visualizing their anatomical relationship in patients with trigeminal neuralgia (TN).
Patients And Methods: This study included 97 patients with primary TN who underwent preoperative 3D constructive interference in steady state (CISS) MRI. Image analysis was performed by an independent observer blinded to the operative findings and then compared with surgical data.
Precipitation patterns are expected to change in the semi-arid region within the next decades, with projected increasing in extreme drought events. Meanwhile, the timing of extreme drought also shows great uncertainty, suggesting that the timing of drought, especially during growing season, may subsequently impose stronger stress on ecosystem functions than drought itself. However, how the timing of extreme drought will impact on community productivity and carbon cycle is still not clear.

However, its performance is largely limited by the low density and poor reactivity of active sites within its basal plane. Here, we report that domain boundaries in the basal plane of monolayer MoS can greatly enhance its hydrogen evolution reaction performance by serving as active sites.

The aim of this study was to investigate the usefulness of peripheral blood routine items in predicting ICU admission and 30-day mortality in CAP patients.
Methods: A retrospective study was conducted.

We report a case of persistent anemia combined with ESR for more than 2 years firstly misdiagnosed as lymphoma. When she received a chest CT scan multiple enlarged lymph nodes were found.
View Article and Find Full Text PDFSREBPs are master regulators of lipid homeostasis and undergo sterol-regulated export from ER to Golgi apparatus for processing and activation via COPII-coated vesicles. While COPII recognizes SREBP through its escort protein SCAP, factor(s) specifically promoting SREBP/SCAP loading to the COPII machinery remains unknown. Here, we show that the ER/lipid droplet-associated protein Cideb selectively promotes the loading of SREBP/SCAP into COPII vesicles.

Background: Community-acquired pneumonia (CAP) is a common infectious disease. Inflammatory reaction and prognosis assessment in adult CAP patients are useful for CAP site of care decisions. Most CAP patients were diagnosed in an out-patient or emergency department, so a simple, cheap and rapidly available measurement to assess inflammatory reaction and prognosis has the prospect of broad application.

Methods: The chest contrast-enhanced CT scan, electronic bronchoscope, and ultrathin bronchoscope were performed leading to the diagnosis of broncholithiasis, open lung lobectomy was done after thoracic surgery consultation.
Results: The chest contrast-enhanced CT scan showed a high-density intratracheal shadow and calcified lymph nodes.
Background: High serum neuron-specific enolase (NSE) level has been in use as a tumor marker; however, some physicians may ignore NSE levels in serum, especially when the patients are asymptomatic. Here we report a case that a 51 year old female patient with no respiratory symptoms who had a NSE level which increased extremely over three months and was eventually diagnosed small cell lung cancer (SCLC).
Methods: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in right pulmonary hilar enlarged lymph node was performed for diagnosis.

TP53 is the most frequently mutated gene in human cancer, whereas tumors with wild-type TP53 develop alternative strategies to survive. Identifying new regulators of p53 reactivation would greatly contribute to the development of cancer therapies. After screening the entire genome in liver cancer cells, we identified lysyl oxidase-like 4 (LOXL4) as a novel regulator for p53 activation.

Precise regulation of ciliogenesis, thus, ensures proper GNP pool expansion. Here, we report that Atoh1, a transcription factor required for GNPs formation, controls the presence of primary cilia, maintaining GNPs responsiveness to SHH.

Much has been known that nutrient inputs can promote growth and expansion of exotic invasive plants in wetlands, and that allelopathic effects of the exotic invasive plants can inhibit the growth of coexisting native plants, contributing to their invasion success. Thus, we hypothesized that allelopathic effects of exotics on natives in invaded ecosystems can be enhanced by nutrient enrichment.

In this work, an electroactive Ni-MOF, assembled by the redox-active ligands 4,4',4″-Tricarboxytriphenylamine (HTCA), a triphenylamine derivatives, as the electroactive source and magnetic ordered NiO clusters as electronic transport nodes, is first designed and applied for electrochemical aptasensing of thrombin (Tb). The designed Ni-MOF probe realizes a stable and sensitive electrochemical signal output based on simple sandwich-type aptasensing because the high-content TCA active sites and good magnetic ordered intermediate of NiO clusters are periodically arranged in well-defined porous structure of the MOF.
